NOTICE
ABB is not be liable for damages or losses caused by the failure to
activate the user lock with a new pass code.
For more information, see "1.9 Cyber security disclaimer" on page 25.
For better cyber security, it is highly recommended that you set a master
pass code for the control panel to prevent the parameter values from
being changed.
• To activate the user lock for the first time, enter the default pass
code, 358, into 16.02 Passcode. This will make parameters
16.24...16.25 changeable. Then enter the old pass code to 16.24
OldUserPasscode and change user pass code in
16.25 NewUserPasscode. In 16.02 Parameter Lock, the user lock
functionality can now be enabled.
• To reopen the lock, enter your pass code into 16.03 Passcode. This
will again make parameters 16.24 and 16.25 visible.
